The surface area of the newly formed right pyramid is multiplied by scale factor 2.
Given that,
Right pyramid,
Edge of the base = 8 cm
Slant height = 25 cm
<h3>What is surface area?</h3>
Surface area is defined as the area of the surface that is uncovered.
Surface area of the right pyramid = 1/2 * edge of the base * slant height
= 1/2 * 8 * 25
= 100 cm²
Now, two dimensions are doubled,
slant height = 50
Edge of the base = 16
New Surface area of right pyramid = 1/2 * edge of the base * slant height
= 1 / 2 * 50 * 16
= 400 cm²
Now, scale factor, the ratio of the surface areas later to the former,
scale factor = 400 / 100
scale factor = 4
Thus, the surface area of the newly formed right pyramid is multiplied by scale factor 2.

Answer:
5 - 35n.
Step-by-step explanation:
5(1 - 7n)
Using the Distributive Law:
= 5*1 + 5 *-7n
= 5 - 35n.
